Internal brake resistor connection (P6.3.3)
With this function it is possible to tell the frequency converter, whether the internal brake resistor is
connected or not. If the frequency converter has been ordered with an internal brake resistor, the
default value of this parameter is Connected. However, if it is necessary to increase braking
capacity by installing an external brake resistor, or if the internal brake resistor is disconnected for
another reason, it is advisable to change the value of this function to Not conn. in order to avoid
unnecessary fault trips.
Enter the edit mode by pushing the right arrow menu button . Use the Browser buttons to change
the internal brake resistor status. Accept the change with the Enter button or return to the previous
level with the left arrow menu button .
Note! The brake resistor is available as optional equipment for all classes. It can be installed
internally in classes FR4 – FR6.
